Lewis Swift discovered IC 5358 = Sw. XI-239 on 14 Sep 1896. His description reads "eF; S; R; 4th of 5 [with IC 5351, 5353, 5354 and 5362]." His position is 3.6' too far southwest (similar offset as IC 5353 and 5354). Howe remeasured all these galaxies and mentions for IC 5358 "binuclear, at an angle of 250°, with a distance of 20"." So Howe discovered IC 5358A, the attached companion on the southwest side, and it should have received an IC designation.

400/500mm - 17.5" (11/1/97): initially seen as a single irregular-shaped galaxy but after careful viewing this double system was resolved into two nearly tangent objects oriented WSW-ENE (the brighter, larger object to the NE is IC 5358). At moments both objects can be seen to have nearly stellar nuclei. This cD galaxy is the brightest in AGC 4038 = Klemola 44.

17.5" (10/25/97): this faint galaxy is the largest of ten viewed in AGC 4038. Appeared faint, fairly small, elongated 4:3 NW-SE, 1.2'x0.9', weak concentration. Nearby is IC 5353 3.9' NW, IC 5354 3.5' W and PGC 72436 2.0' S. Located 16' W of Delta Sculptoris (V = 4.5).

600/800mm - 24" (8/16/12): this cD galaxy is at the center of AGC 4038. At 282x appeared fairly faint, fairly small, elongated 2:1 NW-SE, ~50"x25", sharply concentrated with a bright 15" core and much fainter extensions. A companion (IC 5358A = PGC 72423) is attached on the southwest side, 25" between centers. (IC 5358A appeared faint, very small, round, 15" diameter (similar in size to the core of(IC 5358). IC 5353 lies 4' NW, with a faint companion following.
